IBM Watercools Successor Of Record-breaking Power6 Supercomputer

San Francisco (CA) - IBM announced the replacement for its record-breaking Power 570 supercomputer. However, the Power 575 is a bit more more than just a successor, since IBM decided that it cannot rely on air-cooling anymore and adopted water-cooling instead: To cool every the 16 sockets in the system, IBM uses water-chilled copper plates positioned on top of the Power6 CPUs.

IBM is the latest company to explore water-cooling for data centers, claiming 40% savings in energy consumption and an 80% reduction in necessary air conditioning units in server rooms. Of course, everything is about beating the ecological and financial drum. If 40% savings in power is true, you are looking at a hefty reduction for electricity bill, which, over the lifetime of a server system, is likely to be higher than the cost of a hardware itself.

While water-cooling in servers isn’t entirely new, the next stage of the development at IBM definetely is. The company is working on implementing water-cooling directly onto a chip, using a Direct-2-Die approach. Yes, your wildest enthusiast dreams are coming to life in these professional grade products. Now, if we only could get Intel and AMD to make overclocking CPUs packaged for Direct-2-Die cooling? Imagine an 8-core Skulltrail system without copper heatspreaders, clocked nicely to 5 GHz using integrated water-cooling.

I still remember what my mentor said, in one of my first jobs as a system administrator in a bank: "The day supercomputers start using your amateurish water-cooling technology, hell will freeze over." George, guess what? It probably did.
